ABSTRACT OF THE DISCLOSURE The present invention relates to rinsing systems and more particularly to a system for maintaining optimal concentrations of dissolved solids in a plurality of inter- connected rinsing baths. At least two baths, a first bath and a second bath containing a first rinsing solution and a second rinsing solution, respectively, are connected in flow communication with one another, with the first solution flowing into the second bath. The product being rinsed flows counter to the solution flow. The first rinsing solution is diluted with a make-up liquid to a greater degree than the second rinsing solution. First conductivity monitoring means are placed in contact with the first solution contained in the first rinsing bath. The first conductivity monitoring means are operatively connected to a first valve means controlling the flow of make-up liquid from a make-up liquid source into said first bath. Second conductivity monitoring means are placed in contact with the second solution contained in the second rinsing bath. The second conductivity monitoring means are operatively connected to a second valve means controlling the flow of make-up liquid from the make-up liquid source into said second bath. The first conductivity monitoring means and the second conductivity monitoring means are interconnected so that the second conductivity monitoring means is prevented from opening the second valve means to dilute the second rinsing solution with a make-up liquid unless the first valve is simultaneously open to admit make-up liquid from the make-up liquid source into the first bath.
